Ask Us Friction in Space. Yes, when two surfaces rub together in outer space, there will be friction. Friction is a surface effect and doesn't depend upon there being air. There is also a force like air resistance from the very sparse gas in space, but it will be very, very small, since space is a very good vacuum.he density of matter in our Galaxy is about 1 particle/cm3 (in the disk, with the halo being less dense). The density of matter in intergalactic space (between galaxies) is about 2 x 10-31 gm/cm3, mainly hydrogen. At these densities, I don't think one has to worry about friction.

Gravity (1.38 MB, ogg/Theora format). Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward (or gravitate toward) one another, including planets, stars and galaxies. Since energy and mass are equivalent, all forms of energy, including light, also cause gravitation and are under the influence of it.

StarChild Question of the Month for February 2001 However, if we are to be honest, we do not know what gravity is in any fundamental way - we only know how it behaves. Here is what we do know... Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.

9.2: Friction and Traction 9.2: Friction and Traction. One of the most important principles students must learn before they can begin drivetrain design is that of Friction. FRICTION is the force that opposes motion when two surfaces rub together. It is a reaction force only. It occurs when two surfaces are in contact and a force is applied such they slide along one another. If an object has no forces causing it to try to move, there can be no friction. No applied force, no reaction force.

- Einstein's general theory of relativity explains gravity as the curvature of space-time. This concept can be pictured by imagining space-time as a rubber sheet. The balls on the rubber sheet bend the sheet around them, somewhat as matter bends space-time in its vicinity.

- Gravity, or gravitation, is one of the fundamental forces of the universe. In everyday use, it describes the force which causes objects to fall onto the ground. Newton's laws discusses how gravity keeps the Solar System together and Einstein's theory of general relativity is about the role of gravity in the universe.

Friction This means that sliding friction does not depend on the size of the contact area. When the surfaces are adhesive, Coulomb friction becomes a very poor approximation (for example, Scotch tape resists sliding even when there is no normal force, or a negative normal force). In this case, the frictional force may depend on the area of contact.

What is Friction? Friction is what causes fire to start when you rub two sticks together, as these warriors from a Masai tribe in Kenya are doing. Credit: Paul Banton / Shutterstock.com. View full size image. Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

- Given that, though, what the equation says is simple enough: that what gravity really is is not a force but a distortion of space and time, and that the geometry of space and time depends not just on velocity (as the Special Theory of Relativity had indicated) but on the energy of an object.

What Causes Gravity? It may be hard to believe that the cause of gravity continues to remain one of the great mysteries of science, even to this day. This article will briefly explore our understanding of gravity. We are all familiar with the effects of gravity. The story of Newton being hit on the head by an apple leading to his discovery of gravity is often taught to school children. In short, gravity is a natural phenomenon by which all physical bodies attract each other. For example, the Earth attracts you and keeps you grounded. When you weigh yourself, you are actually measuring the effect gravity has on your body. Although this seems obvious, science still continues to debate what causes gravity.

Friction: Definition and Types Friction occurs in the direction opposite to motion, and because of this, it is a force that affects the motion of objects. When you push a box across the floor, friction works against the box in the direction opposite to the box's motion. When you go down a slide, friction works opposite to your downward movement.

- C. Friction - a force that resists motion and is always present between two moving surfaces. 1  Static friction- keeps a stationary object from moving on a surface when a force is applied to the object.  Sliding friction- occurs when two surfaces slide past each other; slows down the moving object.

9.2: Friction and Traction As seen in the above diagram, when an object is on an inclined plane, gravity is not acting perpendicular to the sliding surfaces. In this case only a portion of the object’s weight would act as normal force. TRACTION: TRACTION can be defined as the friction between a drive wheel and the surface it moves upon. It is the amount of force a wheel can apply to a surface before it slips.

- If there is ever a push, pull, etc., it must be cause by an external force to the object. In this case it is probably frictional, but it could also be the force of gravity pulling down a hill, air resistance, etc. 24. You decide to test your physics knowledge while going over a waterfall in a barrel.

Friction The friction is acting opposite to the ball rolling in the ground. Friction is a force that resists motion. It always acts in the opposite direction to the motion. Friction is caused by bumps on the two surfaces(whic are in contact), rubbing as they slide across each other. Friction means that objects slow down and lose kinetic energy.
